  • From DE 27 10 435 A1 discloses a device on a packaging machine for monitoring, counting and grouping of flat tubular bag packs are known, which are supplied in cycles, lying in intervals, lying and supplied in counted groups another processing station, with defective packages are eliminated.
  • a first conveyor line on which the packages run at intervals, at least one excretory organ for defective packages and a counter for the proper packages are arranged.
  • the excretory member on the first conveyor line is associated with a lateral, transversely directed to the conveyor line nozzle with continuous or intermittent air flow to blow away empty packages laterally.
  • Packages that are not completely separate from one another are ejected on the first conveying path through a separating slide directed transversely to the conveying path and engaging in the spacings of individual packs.
  • the invention is the task underlying, faulty packaging at high Processing speeds despite occurring scattering safe to identify and from the manufacturing process deliberately ejected without this being interrupted got to.
  • the solution according to the invention is characterized in that the separated tubular bags undergo a targeted acceleration after leaving the sealing rollers, so that the distance between two successive tubular bags is increased, which is sufficient to the beginning and the end of each tubular bag with opto-electronic means Detect at high to very high speeds, to detect faulty packaging, to convert into signals and in control commands, with which the identified faulty packaging is pneumatically brought out of its direction of movement.
  • the targeted acceleration is achieved by increasing the speed of the individual tubular bag on a conveyor line by pinch roller and conveyor section of the conveyor belt form a pair of acting, which gives the tubular bags with respect to the sealing rolls by 2 to 4 times higher speed.
  • the tubular bag is moved in the direction of the longitudinal axis of the conveyor belt on a rectilinear path, wherein the tubular bag within the conveying path by means of a hold-down device is forced to coincide with the direction of movement of the conveyor belt movement direction.
  • Another advantage of the solution according to the invention is that its structure is simple, robust and easy to service. It can be easily integrated into existing high-performance packaging machines.
  • the invention is particularly for the Packaging machine sector suitable.
  • Fig. 1 and 2 show the basic structure of the device according to the invention, which is mounted in a only hintingly illustrated high-performance packaging machine for packing candy in flat tubular bags between the sealing rollers 1 and a vertical conveyor 2 .
  • the tubular bag chain 3 is separated by the sealing rollers 1 into individual tubular bag packages 4 and fed to the vertical conveyor 2 with an endless conveyor belt 5 .
  • the conveyor belt 5 is arranged so that it is able to receive the flat tubular bag packages 4 exiting from the nip W of the sealing rollers 1 on a relatively short table-like, horizontal conveying path S.
  • the assembly receiving the conveyor belt 5 is made compact and is located in a housing 6 which receives the drive 7 for the conveyor belt 5 , a small, the nip W associated front guide roller 8, a rear guide roller 8a and a tension roller 9 .
  • the conveyor belt 5 runs in the drive direction A of the sealing rollers 1 in a relation to the sealing rollers 1 much higher speed.
  • a pressure roller 10 is attached to a support 11 of the device according to the invention.
  • the pressure roller 10 is aligned transversely to the conveying direction F of the conveyor belt 5 and forms with the conveyor belt 5 an active pair with an accelerating opening 12 which is dimensioned in its distance from the conveyor belt 5 so that a reaching out of the nip W tubular bag 4 is detected.
  • the pressure roller 10 has a separate drive 13 , which ensures that the pressure roller 10 and the conveyor belt 5 rotates with a relation to the sealing rollers 1 two to four times higher speed.
  • the tubular pouch packaging 4 respectively detected in the acceleration opening 12 by the pressure roller 10 is significantly accelerated, so that the distance between the almost adjacent ends 14 and 15 of two tubular pouch packaging 4 lying in chain on the table-like conveying path S of the conveyor belt 5 increases.
  • the pinch roller 10 may be provided with a roughened, brush-like or rubberized surface for better grasping the tubular bag packages 4 .
  • holders 16 and 17 for the attachment of optoelectronic sensors 18 , 19 and 20 are mounted on the carrier 11 of the device according to the invention.
  • the sensors 18 , 19 and 20 are oriented and aligned so that they are able to detect the beginning 14 and the end 15 of the tubular bag packaging 4 .
  • the sensor 18 and the sensors 19 and 20 have a distance from each other, which corresponds approximately to the longitudinal extent L of the tubular packaging 4 .
  • the sensors 18 , 19 and 20 also have the same height distance from the conveyor line S of the conveyor belt 5 .
  • the sensor 18 is - as shown in FIG.
  • the sensors 19 and 20 are aligned on an axis transverse to the conveyor line S of the conveyor belt 5 and cover the entire width of the conveyor belt 5 to eventual Scattering or deflections of the tubular bag packaging 4 to be detected during their longitudinal movement with the conveyor belt 5 .
  • sensors 18 , 19 and 20 are optoelectronic sensors, preferably infrared sensors, visible light sensors, laser sensors o. The like. Suited. Between the near the pinch roller 10 positioned sensor 18 and the two sensors 19 and 20 , a pneumatically acting hold-down 21 is fixed, the nozzle 22 continuously directs a jet of compressed air to the conveyor belt 5 moving tubular bag 4 .
  • the compressed air jet sweeps over the entire width of the table-like conveyor line S of the conveyor belt 5 and has such a strength that a lifting of the tubular bag packaging 4 from the conveyor belt 5 is reliably prevented.
  • the nozzle 22 is designed to be adjustable, so that the angle of incidence of the compressed air jet can be changed according to the required process parameters.
  • the pneumatic hold-down 21 is connected to a compressed air source, not shown, via an actuator 23 .
  • the trajectory FB is associated with a pneumatic ejector 24
  • the nozzle 25 is oriented so that the compressed air emerging from the nozzle 25 hits the identified faulty packaging, and deflects from its trajectory FB for receiving in a container 26 .
  • the nozzle 25 is designed to be pivotable, so that the deflection beam can take into account the required conditions.
  • the pneumatic ejector 24 is connected via an actuator 27 with a compressed air source.
  • the sensors 18 , 19 and 20 pass their signals to a control unit 28 , which processes the same after digitizing the sensor signals and controls the actuator 27 for opening and closing the gas supply from the compressed air source.
  • Fig. 4 illustrates the principle of the invention Procedure using a high performance packaging machine a packaging speed of 30 packages per Second should be used.
  • the tubular bag packages 4 coming from the sealing rolls 1 are grasped by the pressure roller 10 and the conveyor belt 5 and additionally accelerated with respect to the sealing rolls 1 , whereby the distance B of the spaced-apart ends 14 and 15 of the tubular bag packaging 4 lying in a chain increases.
  • the sensors 18 , 19 and 20 detect the beginning 14 and the end 15 of the tubular bag packages 4 and pass these signals to the control unit 28 , which determines that the corresponding tubular bag packaging 4 has a beginning and an end.
  • the actuator 27 remains closed for the compressed air supply.
  • the tubular bag packages 4 are fed to the vertical conveyor. If two or more tubular bag packages 4 are not properly separated (see also FIG. 2), the sensor 18 can not generate a signal for the end of the tubular bag package 4 .
  • the control unit 28 determines that no signal is present for the end of the tubular bag packaging 4 and issues a control command for opening the actuator 27 .
  • the actuator 27 opens and directs a blast of compressed air on the identified non-separated tubular bag packaging 4 , whereby the latter are deflected from their trajectory FB and discharged into the container 26 .
